ERNEST SHEPARD, F CONCEPTION JUNCTION, MISSOURI LANTERN BURNER- Application filed May 2, 1929. Serial No. 361,193.

to provide aburner so constructed that it will burn kerosene or the like without 'sinok ing and without fanning or jerking out of 1 the flame.

Still another object is to provide a specially designed shield for the burner which encircles the upper end of the wick tube in such a way that air is properly distributed'to the various parts of the flame, in such a manner as to form a good flame of desirable shape and ye; eliminates extinguishment of the flame caused by sudden movements of the lantern.

Still a further object is to provide a wick cylinder in which the wick may be foldedso that the wick does not move around in the oil container of the burner, and the lower end of the wick is always kept in a position close to the bottom of the oil container so as to use the last of the oil therein when the oil gets to a low point.

'Still a further object is to provide an adjustment for the burner with a pair of elements adapted to engage the adjustment to prevent easy movement thereof.

With these and other objects in view my invention consists in the construction, arrangement and combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and

illustrated in the accompanying drawings. in

which:

Figure 1 is a side elevation of a signal lantern in which my burner may be applied and in connection with which it is illustrated.

Figure 2 is a side elevation of the burner. Figure 3 is a plan view of the same. Figure 4 is a Vertical sectional view on the line 44 of Figure 2.

Figure 5 is a vertical section view on the line 55 of Figure 3; and

Figure 6 is an enlarged section view on the line 66 of Figure 2. I

On the accompanying drawings I have used the reference character A to indicate generally a lantern. The lantern A is usually provided with an oil container 10 having a screw-threaded neck in which a burner is mounted. My improved type of burner 0 is indicated generally by the reference character B and has a screw-threaded neck 12 adapted to screw into the container 10. The burner B is provided with a head 14 through which a flattened wick tube 16 extends. Below the neck 12 the burner B terminates in a wick cylinder 18. r The lower end of the wick tube 16 projects into the upper end of the wick cylinder 18.

The wick cylinder 18 has a closure member 20 at its lower end. The member 20 is provided with a flattened sleeve 22- through which the lower end of a wick 24 may extend. The upper end of the wick 24 as clearly shown in Figure 4, terminates at the dotted position indicated by the reference numeral 26. The wick 24 may be adjusted relative to the wick tube 16 by an adjusting shaft 28 carrying spur wheels 30.

Easy rotation of the adjusting shaft 28 is 30 prevented by means of friction elements 32 and 34. The amount of friction may be adjusted by adjusting the clamp screws 36. The member 32 is carried on pins 38 projecting from the burner B.

In connection with the upper end of the flat wick tube 16 I provide a shield C comprising supporting portions 40 extending upwardlyfrom the burner head 14 and a shield portion encircling the upper end of the wick tube 16. The shield portion has inwardly directed parts 42 terminated in outwardly flared parts 44 adjacent theside edge of the wick tube 16. The shield portions C have inwardly flared parts 46 adjacent the fiat sides of the wick tube 16. I

The wick tube 16 is made up of fiat side portions and narrow end portions which are concaved downwardly as clearly shown in Figures 4 and 5 of the drawings. The

purpose of this is so that the wick 24 can be easily trimmed after becoming charred by merely running the end of a match lengthwise across the end of the tube and thereby de ressing the upper end of the wick from si e edge to side edge thereof.

I will now describe the function of the various parts of my improved type of burner, thus far described. The wick c linder 18 is adapted to receive the portion 0 the wick 24 intermediate the ends thereof in'folded formation as clearly shown in Figure 4. This allows the short lower end of the wick'to project from the cylinder 18 for collecting the oil from the container. The intermediate iportion of the wick therefore is not swung around inside of the container 10, but is confined. against such swinging movement. This construction insures that the lower end of 113 the wick will always remain adjacent the botmoving the closure member 20, whereupon thelower end of the wick may be inserted through the tube 22 and the closure member "replaced. Arranging the Wick within the cylinder also prevents twisting of the wick when screwing the wick into the container A The-shield C has outflared portions 44 and Inflated portions 46 as illustrated on the drawings for the specific purpose of cans ingthe flame 48 to assume a desirable forma- :tion as shown on the drawings. The flame \does. not flare out and come to a sharp point, but stops abruptly, so that a flame which is thick clear to the upper end of the flame results. The outflared portions 44 form pockets at the end of the frame through which the combustion of the flame passes. The inflared portions 46 distribute the upward draft of air caused by the heat of the flame in the proper manner for causing the flame to assume a desirable formation. The shield portions being arranged as they are prevent fanning out or choking of the flame when the 65 lantern is swung or when it is jerked up and down or when it is otherwise moved suddenly.

Some changes may be made in the construction and arrangement of my device without 60 departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims, any modified forms of structure or use of mechanical equivalents, which may be reasonably included within their Jigmpe,

ing'split between said partitions.

7 2. In a burner of the character disclosed, a flattened wick tube, a shield therefor surrounding the upper end of the wick tube and spaced therefrom, said shield having notches in the sides thereof extending down from the top edge of the shield and located adjacent the ends of the wick tube, the side portions of the shield between the notches being inflared and the end portions of the shield 35 between the notches being outflared.

3. In a lantern burner, a flattened wick tube, a shield therearound comprising flattened sides parallel with and spaced from the sides of said wick tube and having ainrar; admission openings thercthrough, said shield further comprising imperforate ends spaced from the ends of said wick tube and having inwardly directed portions adjacent the top of the wick tube and outwardly flared porsi' tions above the upper edge of the wick tube.

4. In a burner of the character disclosed,

a flattened wick tube, a wick therein, an adjusting shaft adjacent said tube, a spur wheel on said shaft for engaging said wick to move a! the same longitudinally when the shaft is rotated, means for imposing friction on said shaft to prevent easy rotation thereof, said means comprising a pair of engaging elements between which said shaft is arranged, L screws associated with said elements for drawing them toward each other and supporting rods for said engaging elements, said rods extending from and supported by said burner and said elements having sleeve porr tions positioned on said rods.
